As a further setting of the utility model, be provided with the depression bar that is used for drive button to press on the waterproof case, the depression bar articulates the setting and is in on the waterproof case.

Adopt above-mentioned scheme, the articulated depression bar that sets up on waterproof case can continue the depression bar that will set up originally in the body outside through setting up in order to be used for pressing the button on waterproof case for waterproof case possesses the function of depression bar simultaneously.

As a further setting of the utility model, the both sides of depression bar are buckled and are formed with the connection piece, be provided with the hinge hole on the connection piece, be provided with on waterproof case's the lateral wall with the articulated complex of hinge hole articulates the piece.

Adopt above-mentioned scheme, set up the connection piece that articulates on articulated piece, on the one hand be for the convenience of the depression bar installation, on the other hand can make the depression bar can more conveniently press the button, and articulated setting makes the difficult rupture of depression bar damage.

As a further setting of the utility model, the one end that the depression bar is equipped with the connection piece is provided with and is used for supporting the flexure strip that presses on waterproof case.

By adopting the scheme, the elastic sheet can play a limiting role on the pressing rod, so that the pressing rod is prevented from rotating or vibrating in the opposite direction of the button, and meanwhile, the pressing rod is convenient to reset.

As a further setting of the utility model, the lateral wall of body is provided with the direction inclined plane of installation is established to the waterproof shell cover of being convenient for.

By adopting the scheme, the guide inclined plane is convenient for the waterproof shell to be sleeved, and the installation efficiency is improved.

The present invention will be further described with reference to the accompanying drawings.
